Checks

  • i
    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: pdns01.domaincontrol.com, pdns02.domaincontrol.com.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: ns5.dnsmadeeasy.com, ns6.dnsmadeeasy.com, ns7.dnsmadeeasy.com. ns5.dnsmadeeasy.com, ns6.dnsmadeeasy.com, ns7.dnsmadeeasy.com, pdns01.domaincontrol.com, pdns02.domaincontrol.com report NS ns5.dnsmadeeasy.com ns6.dnsmadeeasy.com ns7.dnsmadeeasy.com pdns01.domaincontrol.com pdns02.domaincontrol.com.
    #7
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 5 IPv4 /24s and 5 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS16552 (DIGICERT - Tiggee LLC, US): 6 addresses; AS26496 (AS-26496-GO-DADDY-COM-LLC - GoDaddy.com, LLC, US): 1 address; AS44273 (GODADDY-DNS - Host Europe GmbH, DE): 3 addresses.
  • i
    All nameserver names under .com
    All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.
    #12
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
